A data quality owner asks to standardize country codes before aggregating regional sales. The team plans to implement this change: Use governed mappings to normalize country values before grouping. Which result best verifies the intended outcome?
Canonical lookup mapping prevents one logical category from appearing as multiple inconsistent groups. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: The transformed output contains one row per intended nested item with all parent keys retained. It does not demonstrate the specific required result: The report groups all known country synonyms into the single approved code.
That observation would verify a different goal: All expected records appear with consistent types after normalization. It does not demonstrate the specific required result: The report groups all known country synonyms into the single approved code.
That observation would verify a different goal: A test row with known revenue and cost yields the correct gross margin value. It does not demonstrate the specific required result: The report groups all known country synonyms into the single approved code.

Two fact tables can have many records per customer, so a direct key join multiplies rows. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: Reconciled invoice totals match the exact expected currency precision. It does not demonstrate the specific required result: Totals match independently computed sales and returns measures at each month.
That observation would verify a different goal: A single month filter applies consistently to orders and returns. It does not demonstrate the specific required result: Totals match independently computed sales and returns measures at each month.
That observation would verify a different goal: Sales totals reconcile and a product dimension filter propagates to the intended fact rows. It does not demonstrate the specific required result: Totals match independently computed sales and returns measures at each month.
A business unit wants to read existing cloud storage files in a lakehouse without making another full copy. Which implementation decision best addresses the stated requirement?
Shortcuts expose referenced data through OneLake without requiring a full duplicate copy. The proposed action directly targets the problem described in the scenario.
Enable a supported Eventhouse data availability/integration path to OneLake as appropriate. is an approach for a different requirement: Eventhouse and OneLake integration can make compatible event data available for cross-workload analytics. In the present case, shortcuts expose referenced data through OneLake without requiring a full duplicate copy.
Use Dataflow Gen2 with supported connectors and Power Query transformations. is an approach for a different requirement: Dataflow Gen2 supports low-code data preparation and destination loading within Fabric. In the present case, shortcuts expose referenced data through OneLake without requiring a full duplicate copy.
Route supported stream data through Eventstream into an Eventhouse KQL database. is an approach for a different requirement: Eventstream carries event data into real-time destinations such as an Eventhouse. In the present case, shortcuts expose referenced data through OneLake without requiring a full duplicate copy.
A SQL warehouse has an existing dimension table and a modeling team proposes creating a second copy in every workspace. The team plans to implement this change: Prefer an authorized shared data source or OneLake reference over redundant unmanaged copies. Which result best verifies the intended outcome?
Reusing governed data reduces divergent definitions and unnecessary data duplication. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: After two runs the destination contains the new records without duplicating previously loaded keys. It does not demonstrate the specific required result: Two consumers read the same authoritative records and changes are reflected through the supported access path.
That observation would verify a different goal: A new ingestion run succeeds under the correct identity and shows recently added source records. It does not demonstrate the specific required result: Two consumers read the same authoritative records and changes are reflected through the supported access path.
That observation would verify a different goal: An authorized engineer reads sample source records; a denied principal cannot use the connection. It does not demonstrate the specific required result: Two consumers read the same authoritative records and changes are reflected through the supported access path.
A team needs notebooks and a data lake architecture, not primarily SQL procedures over structured tables. Which implementation decision best addresses the stated requirement?
A lakehouse combines OneLake files and Delta tables with notebook-friendly engineering. The proposed action directly targets the problem described in the scenario.
Choose Eventhouse with KQL database storage for real-time/event-style analytical workloads. is an approach for a different requirement: Eventhouse is designed to ingest and analyze event or log data efficiently with KQL. In the present case, a lakehouse combines OneLake files and Delta tables with notebook-friendly engineering.

Early row filtering reduces unnecessary downstream movement and compute when folded appropriately. The proposed action directly targets the problem described in the scenario.
Project only required columns in the source query or transformation. is an approach for a different requirement: Column projection limits the data carried to the requested output and avoids unused payload. In the present case, early row filtering reduces unnecessary downstream movement and compute when folded appropriately.
Create a typed derived expression for revenue minus cost in the transformation layer. is an approach for a different requirement: A consistent derived column makes the business calculation reusable at the intended grain. In the present case, early row filtering reduces unnecessary downstream movement and compute when folded appropriately.
Create a transformation expression that concatenates name components with null handling. is an approach for a different requirement: Enrichment should handle optional source fields explicitly to avoid unexpected null results.
